PROCESS OF MAKlNG LAUNDRY-SOAP, 80C.

SPECIFICATION forming part of Letters Patent No. 347,027, dated August10, 1886. Application filed December 2, 1885. Serial No. 184,456. (Nospecimens.)

To all whom it may concern:

Be it known that I, NICHOLAS J. CLUTE, of the city of Chicago, in theState of Illinois, have invented a new and useful Process in MakingLaundry, Shaving, Toilet, and other Soaps, which process is fully setforth in the following specification.

This invention relates to that class of processes used for makingdifferent kinds of soaps and it consists in the use of an entirely newingredient in soap-making never before used or known. The new ingredientis the tankwater formed in the rendering of lard, tallow, or other fats,which water has heretofore had little or no commercial value. I havediscovered that the water possesses in a high degree all the essentialproperties in making soaps when used in connection with other adipose or01eaginous substances usually used in soap-making or alone as a base tounite with the alkali. The usefulness of this discovery consists inutilizing as an article of commerce a heretofore comparatively worthlesssubstance, in its cheapness, in the combining qualities which itpossesses, rendering saponification complete in the mordant property ofits inherent ammonia, which also renders it remarkably detergent. Saidtank-water, when reduced by evaporation, is of a sirupy consistence, andholds in solution about twenty per cent. of solid matter, and of thissolid matter about fifteen to twenty per cent. is nitrogenizedsubstance, furnishing the ammonia. Said water has strong detergentproperties when used alone, either with or without the use of alkali.

The following is about the proportion used for making soaps by my newprocess: One hundred pounds of tank water, after it has been reduced byevaporation fifty per cent., ninety pounds of tallow, and fifteen ofresin,

with an amount of caustic soda sufficient to,

render saponification complete. The detail of manufacturing and handlingis the same as in any or all soaps.

I do not intend to confi no myself to the use of the tank-water inconnection with tallow and caustic soda, as above stated, as it can beused with any other adipose or oleaginous substance and with any otheralkali used for making soap. The resin can also be omitted when it isdesired to make white soap; nor do I want to confine myself to the exactproportions mentioned above, but claim the right to vary the proportionsof the materials, as it is customary with soap-1nakers. Soap may be madewith the tank-water alone as abase in connection with an alkali or inconnection with other oily substances in different proportions with analkali; but I have given the preferable proportions for making cheaply afirstclass soap with the new material.

What I claim as my invention and discovery, and wish to secure byLetters Patent, is-

1. The making of soaps by the combination of the so-called tank-water,or the water formed in the rendering of lard, tallow, or other fats,with resin and an alkali, substantially as set forth.

2. The combination, in soap-making, of the so-called tank-water, or thewater formed in the rendering of lard, tallow, or other fats, withresin, tallow, or other adipose or oleagi' nous substances usually usedin making soaps, and an alkali, substantially as described.

In the making of soaps by the combination of the so-called tank-water,or the water formed in the rendering of lard, tallow, or other fats,with tallow or other oleaginous or adipose substances usually used inthe making of soaps, and an alkali, substantially as described.

It is hereby certified that Letters Patent No. 347,027, granted August10, 1886, upon the application of Nicholas J. Olute of Chicago,Illinois, for an improvement in the 1 Process of Making Laundry Soap,850., was erroneously issued to said Glute; that the said Letters Patentshould have been issued to said Olute and James M. Anbery and Preston B.Rose, said Aubery and Rosebeing assignees of two-thirds interest in saidinvention; and that the said Letters Patent should be read with thiscorrection therein that the same may conform to the record of the casein the Patent Office.
